The PowerGEN GM Black Short 90amp 12-Volt alternator is a heavy-duty electrical generator designed for vehicles requiring reliable power output in demanding conditions. Built for trucks, off-road equipment, and tactical vehicles, this one-wire alternator eliminates the need for external voltage regulators, simplifying installation and reducing wiring complexity. The 90-amp output capacity makes it ideal for operators running auxiliary power systems, lighting, communication equipment, or winches alongside factory electrical loads.

This alternator features a durable aluminum case with black powder-coat finish, providing corrosion resistance in harsh environments and extended service life. The single belt pulley design ensures straightforward mounting and minimal maintenance, while the compact short-frame dimensions allow fitment in tight engine bays. The 90-amp rating delivers sufficient charging capacity to keep deep-cycle batteries and auxiliary systems powered during extended off-grid operations, making it essential for vehicles equipped with modern electronics, communication systems, or power-hungry accessories.

Operators upgrading or replacing aging alternators will benefit from the PowerGEN's reliable performance and bolt-on compatibility with standard 12-volt vehicle platforms. The one-wire configuration simplifies troubleshooting and reduces installation time compared to multi-wire regulators. Weighing 14.35 lbs, this alternator integrates cleanly into most engine compartments without requiring custom brackets or modifications. Suitable for restoration projects, performance builds, and tactical vehicle platforms that demand consistent electrical output under continuous load.
